ASSOGIATING MECHANISM FOR WEB YRINTING AND FOLDING MACHINERY.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed June 19, 1911. Serial No. 633,913.

To all whom it may concern:

Be it known that I, ROBERT CUMMING AnNANn, of Barrington street, Shields, in the county of Durham, England, printers engineer, have invented certain new and useful Improvements in Associating Mechanism for WVeb Printing and Folding Machinery, of which the following is a specification.

My invention consists in an improved arrangement of turning or angle bars, by which a large-number of printed webs can be associated or superimposed previous to their being folded and made up into the form of newspapers or periodicals of various sizes.

. In a multiple web machine, printing webs of What is known as double width, there is difiiculty in arranging th t'iirning bars so that the various webs can be associated together when their number is above four, and

the devices now in use are complicated and occupy much space and necessitate long travels of the webs.

My arrangement of associating devices occupies less space than mechanism for the same work has hitherto occupied, the length I of travel of the webs can be shortened, and,-

the number of webs operated upon can be increased by simply duplicating the mechanism.

Speaking generally, two-turning or angle bars are required to associate two half webs. These two turning bars-may consist of stationary round bars set parallel to one another and at an angle of 45 degrees to the direction of travel of the webs as they leave the rintin press and before they are slit longitudinal 1y. Turning bars can also be arranged at an angle of 90 degrees to each other and placed in the machine so that their a ex stands in the direction of the longitut inal line of the printing machine. I will call these double turning bars. I select the latter type of angle bars to form part of my arrangement of novel associating I place these double turning bars in horizontal tiers, one setabove the South their previous course.

other set, preferably with their apices pointing in the direction of the printing press to which they are attached. Each 'web is carried to its corresponding double turning bars, and just previous to reaching the turning bars, the wcbs are longitudinally slit in the well-known manner. Dealing with, say, the top web, one half of it is carried to the right around the right hand bar, the other to the left around the left hand bar. The direction of travel of the two half webs has thus been changed to that of right angles to The half webs are nextcarried around registering or guide rollers and are brought back underneath the angle bars, and each is carried around a roller which changes the direction of travel of the webs to that of a vertical descent. By this arrangement the two half webs can descend throu h between any reasonable number of angle bars arranged in relatively the same horizontal position. The next lower half webs are carried in a manner similar to the first around their corresponding double turning bars, registering or guide rollers and downwardly deflecting rollers and descend in a erpendicular direction outside the two halt webs descendin from the top tier of turning bars. The halfwebs on the next lower tier are dealt with in precisely the same manner, and these in turn come outside the four half webs from the upper turning bars. It will be readily understood that more webs can be associated in this manner by repeating the mechanism described.

In superimposing a number of webs of paper, it is usually desirable that the Webs shall all be kept apart until they arrive at a part of the machine where they all ass partly around an associating roller, usually a serrated driven roller, against which they are pressed firmly by rubber disks set where the margins come. The pressure of the rubber disks on the Webs against the driven serrated roller draws up the slack webs and causes the whole number thus associated to pass-in register to any further form of foldmg mechanism that might be embodied in the machine.

The keeping apart of the webs until they reach a certain point while at the same time passing down between and clear of the lower turning bars, is secured by the present invention, because the edges of the half webs as they are carried to the left and right and pass the rollers which turn them down-- ward into a perpendicular direction, they can pass between the turning bars at a certain distance apart, and, at the same time, clear of the lower turning bars in their descent. For instance, if the angle bars are made four inches in diameter, the half webs can pass through between the angle bars, at a distance of about'three inches apart from each other without fouling the lower angle 5 bars. a Instead of the half webs returning under the turning bars to which they appertain, they can return over the same, it being only necessary to arrange the lateral guide rollers and the downwardly directing rollers accordingly.

When I speak of the webs descending vertically' or perpendicularly I do not mean that in its exact mathematical sense, as the webs, when kept apart, have to approach each other and in order to do so must depart from a strictly perpendicular path.

By arranging the turning bars in the mannerdescribed much space is saved, each so half web has the same length of travel, all

the half webs are fed through the apparatus in the same way, and the attendants can get to the turning bars with great facility and handiness.

The accompanying drawings illustrate by way of example the application of the invention for folding and associating three double width webs on a printing machine,

a and represent the folding'and associating 40 mechanism diagrammatically.

Figure 1 is a side elevation of the folding and associating mechanism; Fig.2is an end 4 isfa detail plan view on a larger scale, and

illustrates how trend of the webs away from the apex of the angle bars in turnin enables them to return and be directed ownward between the angle bars below without fouling the same. Fig. 5 is a part end'view 'showing a slight modification in which the half webs are led in under the angle bars instead of over them. Fig. 6 is a similar view showing a modification indicating that the half webs can be returned above the turning bars to which they appertain, instead of under the same. A, B and C represent the three printed webs of paper as they pass to the folding and associating mechanism. These webs pass in the usual way around registering rollers a, b, a to the customary slitting mechanisms consisting of driven grooved rollers d, e, f coactin g respectively with rotary driven cutters d, e, f which slit the webs just before they pass on to the turning bars elevation thereof, and Fig. 3 is a plan. Fig.

D D,- E E, F F. The gearing for communicating the drive to the cutters d, e, f. is omitted, it being of the usual kind. The turning bars D D, E E, F F are arranged in pairs united at right angles, with their apices in the longitudinal direction of the corresponding web, and the pairs of turning bars are superimposed.

The halves A A, B B, C C of the slit webs pass respectively to right and left around the bars D D, E E, F F, which divert them into a direction at right angles to their original line of travel. In Figs. 1 to 3 the half webs are shown as led over and around the turning bars, whereas in Fig. 5 so they are led under and around them. From the turning bars the half webs are led around registering rollers G G mounted on the framing K at the sides of the machine and serving to direct the half webs A B C back toward the longitudinal mid-plane of the double turning bars, and the half webs are then carried respectively around pairs. of rollers H H,'I I, J J, which divert the half webs downward, A A passing between the turning bars E E and F F, and B B between the turning bars F F, and the six half webs passing to the. associating rollerL. It will be seen that the top half webs A A pass down between the half webs B B next below, and these pass down between thenext lower pair of half webs C C, and so on for the desired number of webs. The rollers H H, I I, J J, of each pair should be at a suflicient distance apart from each other for the webs to be kept'apart until they reach the associating mechanism, and on the other hand they should not be so far apart that the webs in their descent will foul the turning bars below. By' way of example, if the turning bars are four inches in diameter, the rollers H H may be aboutthree inches apart, and the rollers I I and J J of the pairs below may be at the same distance or (as shown) at a somewhat greater distance 11o apart.

From the mechanism described the six webs pass to an associating device of the usual kind, consisting of a serrated driven roller L against which the webs are pressed by rubberdisks L set where the margins come. The slack webs are thus drawn up and associated so that they pass on 'in register to any further mechanism that the machine may comprise. In Fig. 2 the six 1% webs are shown passin on to the taper fold former M of an ordinary folding mechanism.

Reference to Fig.4 will show more clearly how the natural trend of the edges '9 of the 12 half webs away from the apex of the turning bars enables them when returned inward and directed downward by the'rollers, to pass down clear of the turning bars below. lit will be seen that this lateral and rearward diver ence of the edges 9 enables the circumerence of the downwardly directing rollers (H H, Fig. 4) to extend sufficiently far inward that the edge 9 on returning and. passing downward around this roller, will descend clear of the turning bar below, while at the same time the webs can be kept apart in their descent.

The drive is imparted to the slitting mechanisms and associating mechanism in any usual way. In the drawings this is shown as efi'ected by a vertical shaft h driven from any suitable part of the machine. A bevel wheel 7: on this shaft drives a shaft j which through bevel gears 70 Z drives the associating roller L. The motion is imparted to the slitting rollers 03 e f from another bevel wheel m on the vertical shaft h. The bevel wheel m gears with a bevel wheel m on the shaft of the slitting roller f, and the motion is transmitted from f to the slitting rollers e (Z by toothed gearing n 0 p q 1' of which the wheels n p and 'r' are mounted on the respective slitting rollers.

In Fig. 5 the half webs are led in under the turning bars instead of over them, the only ditfei'ence in construction being that correspondingly larger registering rollers are required.

In Fig. 6 the half webs after passing around the turning bars return inward above the turning bars to which they appertain, the registering rollers G being suitably located for this purpose and the downwardly directing rollers H being located above their corresponding turning bars.
